White smoke coming from my Perkins 4108?
We just came back from a motor on our sail boat. Were at 2000 rpm’s going and 2100 rpm’s coming home. Few miles each way. When coming home it was a bit of nasty weather wise. Two blade prop and a 36 foot boat 1700lbs. Why would we get white smoke from the exhaust and what does it indicate? I thought it was from overheating but the Perkins never got over 190 if the gauge is correct. About a 1000 hours on the 1978 motor.
